' My invention-relates to an improved m chine for shocking grain in the field as it is delivered from theharvester and binder, to Which said machineisattached. i The main object of my invention is to proyide means for receiving the sheavesori bun- Another ob ect of my invention is jto ie 'Vid6 means whereby the buttends of the shocks are spread as the sheaves-aredeposited on the ground, giving the shocks agreater base area than would otherwise-be presented, and thereby insuring self sustainment of the T shocks in vertical position.,'

Afurther object of my'inve'ntion is to prof vide means whereby the shocks are ,com-[ pletely surrounded when the receptacle is tilted and in the depositing positiomthereby '25 preventing displacement, from the substantial vertical position, due to ;the centrifugal force of theoutermost bundles provided, in the tilting of the receptacle.

A still further object of; my inventionis ,the novel construction and arrangement of parts which enables the sheavesor bundles to be deposited in shock formation "with the least amountof traction effort, thereby reducing the tendency to retardjthe forward ;1novem'ent of the machine.

Another object is the simple and-coinparatively inexpensive constructionof ma-V chine, which comprises. a minimum number of parts operating'in' a highly'efficient man-" ner; r I v With the foregoing objects-and other fea tures which will appear inthe following description, taken-in conjunctionvwith the ac-,

a turned down side 5 permitting the entrance- {7 I of the bundles from the binder. Extending part ay in; and along the base-oflth'e trough is an endless chain 6 which passes over" sprocket 7,-fiXed to the shaft8 that is jean naled between the auxiliary framesp 9 and 10. The chain .6 travels in the direction'indi catedby arrows,'and passes over the sprocket 11 at the upper end'of the inclined trougli'gl2 'i which is supported by the members 13 13,

An' idler sprocket 14, aiding intlie support of chain 6, is located at the lowerend'lofthe inclined trough; Spaced along chainrdarex carrier blocks 15 forming an elevator for service in raising the sheaves Within the inclined vtrough 12'.

' The chain 6 is driven by the traction 'wheel 16 whichiis fixed to the shaftl? Q saidjsha'ft v being journaled in suitable brackets 18 and] 19.; Fixed to the, shaft 17 and lying 'between the auxiliary frames 9 and lO is. a gear 20, meshing with a gear 21, fixed to the shaft 22,"

Y that is suitably supported by journals mount edonxtheauxi'liary frames .9 and'lOf Asthesheaves leave the elevator they are: d deposlted'bn a VL-shaped platformi26=that is ice supported by members 13. 'One side 2'? of the platform 26, which is directly under the trough 12 is rigid, while the other side of the platforn128 is yieldable on the pivot 29 against the tension of springs 30 that are arranged to maintain the side 28 in contact with the rigid part 27. During the tilting of the receptacle the side 28 is locked, by means of a swinging bolt 31, securedto the member 28, said. bolt passing through a hole 32 in theframe 33;

tacle 40. The sheaves are 'carriedup the elevator butt ends first and therefore will stack within the receptacle l0 butt ends to the rear. V

The tilting of the receptacle is .accom plished in the following manner: Fixed to the shaft 17 is a sprocket 37, which by means of a chain 38, drives the sprocket 39 that is freely rotatable on the shaft l0, journaled in suitable bearings 41 and sleeve 42, which is suitably supported by bearing 43 on the main frame 1. The sleeve i2 is slidable upon the shaft 40 and in the bearing l3 and carries a clutch member 1% inside the frame 1 which engages the complementary clutch member 4:4 carried by the sprocket 39. An annular groove 15 in the clutch member 44 is adapted to receive the pin e6 fastened to the member 47, which serves to move the clutch members 41% and 4% into engagement under control of the operator. Suitable connecting means, (not shown) may be employed in performing this operation. I Se cured to the sleeve 42, outside the frame 1 is a crank 48 connected to a link 49. A member 48. fixed to the frame 1, lies in the plane of rotation of the crank 48 and serves to antomatically disengage the clutch members 4-4 and 44 at the completion of each cycle. The link 49 is connected as at 51 to a crank 52 formed integral with a gear sector 53, pivoted at 54, and supported by suitable bearings on.

the main frame 1. Also mounted by suitable bearings on the frame l is a shaft 55, to which is fixed the gear 56 meshing with the sector 53. Within the frame 1 and fixed to v the shaft 55, is a crank 57, connected to a link 58, which in turn is fastened as at 59 to the base of the receptacle, 40.,

It will be noted that by the engagement of the clutch members 44: and 44 the receptacle will be tilted about its axis 50 and 50. The crank 48 pulls link 49 and rotates shaft 55, by

' reason of the crank 52,.sector 53 and gear 56,

one cycle the crank 57 turns 180 degrees in one direction and returns 180 degrees in the opposite direction to normal position.

The radial ratio between the crank 57 and the receptacle 10 due to the arrangement of the relative parts is such as to causethe receptaclellOto turn one-half so much as the crank 57. That is, when the crank 57 has turned 180 degrees in one direction and re turns, the receptacle at that time turns or tilts 90 degrees and returns.

In depositingrthe shock on the ground the rotating movement of the receptacle is likely to upset the vertical stability and cause the rear bundles'to fall rearwardly. To overthe member 60 to form a rear wall in order the receptacle is in the depositing position shown in Fig. 2. .VVithout this wall the rear would remain open. 7

The member 60 is slightly arcuate and is secured to arm 61, pivoted at in suitable bearings 63, supported by the braces 61 Secured to the arm 61 is a crank 65 which is connected by the link 66 to the crank 6? on the shaft 68, journaled in'suitable bearings, supported by the cross-beam 69. Fir-ted to the shaft 68 is a crank '70, connected by link 71'to a crank 72 fixed to the pivotal 50 of the receptacle. As shown in f2, and by the arrangement of the relative parts, the member 60 is in place at the depositing position and is quickly removed on the return to normal of the receptacle so as not to interfere with the shocks as the machine continues its forward travel.

In order to spread the butt ends of the shock, the receptacle lO consists of a bottom 7 5 having an inclined trough 7 6 along the longitudinal center thereof as clearly shown in Fig. 4. Arranged along the rear edge of said trough 7 6 are a series of slightly arcuate members 77, pivoted as at 78, shown in Fig. 6. In the normal position of the receptacle the members are arranged in a transverse vertical plane. The members 77 are capable of swinging 180 degrees. During the tilting of the receptacle the butt ends of the bundles, due to their weight, will tend to swing the members 77 against the action of springs 79 until said members 77 are swung about degrees and thereafter they will snap from under the bundles and thereby spread the butt ends. The arrangement of the parts in this action is clearly shown in Fig. 6. The members .77 spread the forward butts of the shock. I

' In order to spread the butts at the sides of the shock, members 80, which are slightly arcuate, are Vertically disposed and arranged in a transverse plane and are hinged at 82 to to surround the shock on all four sides when weight-of the bundles will tend [to swing the members 80 against the action of'springs 88 until these members 80 are swung about 90 degrees, and thereafter they snap from under the bundles, therebyaiding thexsp'read.

- ing ofthe butt ends. r

7 Upon the return of the receptacle to the; normal positionthe members 8 0, now being in the spread or open position will come in contact with abutments 91 which will 'cau se the members 80 to snap back to their normal position. r

In order to return themembers 7 7 to their normal position,there are a series of bars 92, connected to one arm of a bell crank 93, the other arm of which is connected as by link 94 to a crank 95 fixed on the shaft 55. Each of the bars 92 is supported at the rear end thereof byv a lug 9 6 arranged under its respective member 77 The bars 92 are arranged to cause the members 77 to snap back to their normal position upon the return of vthe receptacle. The bars 92 do not interfere with the snap opening of the. members as they are quickly withdrawn from the lugs 96 7 due to the compound action of the crank55, plus the effect 'offthe ofiset of bell crank .93

relative to the pivot of the receptacle 50, and conversely-the bars 92 do not begin toact on the return to normal of the receptacle until nearly'the completion of return of the recep tacle.

From the foregoing description it will be 7 seen that I have'devised a highly efficient shocker that is capable of forming and depositingthe shocks so that they will remain deposited in a vertical position. Variationswithin the spirit and scope of my invention are equally comprehended in the foregoing description." v
